tocK FOR nnivrr CARS.

Application filed; Jul 2's,

This-invention relates to locks for dump cars and the like and has for an object to provide a lock embodying new and improved features of convenience in Operation A. further object of the invention isto provide a lock of improved type embodying new and improved features to facilitate the closing of the door. I

A, further object of the invention is .to

provide in a lock'new and improved fe.a- 'tures whereby the door may bemaantamed in a partially open position for the purpose of discharging a small volume ofthe material from. the-car as the car is being moved v along.

W'th these and otherobj'ects in View; the invention comprises certain novel parts,v elements, units, combinations, constructions," 1 mechanical movements and functions as disclosed in the drawings together with mechanical and functional equivalents thereof as will be; hereinafter more. fully described and cl'aimed. v

In the drawings;

It-iswell understood that dump cars are; now in use embodying inclined hopper orchute bottoms indicated I at 10. withhinged doors-asv indicated atl l, the opening o-f which dischargesjthe material from the ho-p per bottom, 10. I i

provide attaching the hasp lfi thereto by and the hasp is provided with. one or more shown at Figures 1; 3', Land 5 which is thebody. 12.

192a Serial No. 125,456.

and at the same timeto make the unlocking of'thedoor convenient and" easy.

The present invention comprises a body 121 which attaches to'the end of the hopper bottom sections which in effect areusually' the sides of the car, such attachingrmeans being by any usual and ordinary mechanical devices, such as the bolts 13-, which-are inserted through openings 14. provided forthe purpose.

[The body 12is provided with an opening or: passage-15 through which the hasp 1-6 attached tothe door passes.. This hasp-16 is preferably attached to; a structural steel. or iron bar 17 which extends throughout the length of the door and itis the intentto: use 7'51v one: of these. locks uponeach end, it being understood that each is the equivalentof the other an d'o'nly one isshowns This'loar L7- .extends' beyond the end-of the doorto:

means of a block 18 to which the hasp is. hinged or pivoted-asat 19. Y K ,Mounted to slide in the: body 12, and to; transect the opening 115 is a lockmmber 2 0 I slots 21 properly proportioned -toaccom: modate the key 20whenthe-hasp: has been drawn: or otherwise moved intosuch. posi tion as to completely ClOSQftl'lG doori in the p'osition shown. at Figures 1* and, 3., This lock 20. is provided with an overhang head 22 'sothat a fhammer as indicated at 23, for

otherfconvenient utensil, may be used. to drive the lock upwardly from theposition locked position; to the unlocked position, as

- shown at Figure 2.: In locking the door,. the hammer. may also be employed upon the top of the overhangihead 22 for drivingtheq lock home; For this purpose, the lock is preferably provided with a chamfered-corner 23, as shown moreparticularly atFigure 6, for -engagingthe edge of the.slot 21" and drawing the hasp. and. thew-door- 0011-.

nectedtherewith more tightlyto closedposi tion.- The lock is also provided with? a slot 2t-thr0ugh which a pin 25-is inserted-to limit the movement of the lock and also prevent its complete. displacement from the "To add to-the security of the lock, a key 26 is employed having a tongue 27 properly positioned and proportioned to enter the groove 28 of the lock whenthe lock 20 is in seated position as indicated at the fig ures showing the several members locked. This key 26 is also provided with a slot 28" through which a pin 29 is inserted for the purpose of limiting the movement of the key and also preventing its displacement. It will be noted,-especially from Figure 3, that in locked position the slotted end of the key extends beyondthe body 12 so that a hammer or other implement may be employ-ed to drive the key 26 in the direction indicated by the arrow at Figure 7, which will disengage the tongue 27 from the groove 28, which is a step preliminary to driving the lock 20 from its seat by the engagement of a hammer or like implement under the overhang head 22.

The hasp 16 is also provided with one or more perforations 30 through which a bar 31 may be inserted as a leverage bearing against the body 12 to draw the door 11. to closed position. The bar or its equivalent may also be employed inserted through one of said perforations to maintain the door in partially open position so that, as before mentioned, the contents will be slowly discharged as the car is moved or for any other purpose,

it may swing outwardly with the door leav-. ing the body entirely or by the insertion of the bar 31 in one of the perforations 30 its movement may be limited. WVhen the material has beendischarged and it is found desirable to close the door, the door isswung to position and the hasp 16 entered into the opening 15 simultaneously upon each side ofthe car.' Under ordinary conditions, the door may be simply swung to shut position manually, whereupon the lock 20 may be forced home either by the hand or a driving 1 implement and secured in such position by the key 26 which may be driven home by the use of a hammer.

What I claim to be new is:

'1. The combination with a dump car em bodying a hinged door, of a lockseoured to the end adjacent the door and comprising a body having a passage therethrough, a hasp carried by the door adapted to be inserted through the passage of the body and provided with a perforation, and a lock member slidably carried by the body, properly proportioned and positioned to enter and pass through the perforation of the hasp. v

2. The combination with a dump car embodying a hinged door, of a hasp pivoted to the door beyond the end of the door, a lock body having a passage therethrough, a hasp adapted to be connected to the door of a car and proportioned to pass through the opena ing of the body and provided with a pen foration, a lock slidable in the, body and 3. A lock for dump cars comprising a proportioned to pass through the perforation of the hasp, an overhanging head formed upon the lock adapted to facilitate the driving of the lock in either direction, and a key properly positioned toretain the lock in locked relation to the hasp. i i

41. A look for dump cars and the likecomprising a body having a passage there through, a lock slidable relative to the body and positioned to transect the passage, said lock being provided with a slot, a in inserted through the slot adapted to limit the movement of the lock, and a key member movable transversely relative to the lock adapted to hold the lock in locked position.

5. A look for dump cars comprising a body having a passage therethrough, a lock slidable in the body and proportioned to transect the passage, a hasp proportioned'to enter into and through the passage and provided-with a preferably properly proportioned opening to receive the lock, a key member slidable relative to the lock, and tongue and groove connection between the key and the lock.

6. A look for dump cars comprising; a

slidable in the body and transecting the passage, means limiting the sliding movement of the look, a hasp properly proportioned to pass into andthrough the passage and provided with an opening properly pro portioned to receive the lock, a key slidable transversely relative to the lock, and a tongue formed upon the key adapted in one posi tion to enter a complementary groove on the. lock and maintain the lock in locked position.

I I 8. A lock for dump cars comprising a body having a passage therethrough, a hasp adapted to be attached to the door and pro vided With a plurality of openings, a lock member carried by the body properly proportioned to interengage with one of said openings to maintain the door in closed position, said hasp being also provided With other openings spaced vfrom the said lock receiving opening, and a bar adapted to be inserted through one of said last mentioned perforations to maintain the door in par-, tially' open position. 1
